The Mentalist, Season 1

The Mentalist (2008-) is an American crime procedural television series about a private investigator who uses his skills of observation to help the police solve crimes.

You and Miss Duane came up here to have sex in the boss's office.

That is absurd. Why would I do such a stupid thing?

Because it's forbidden and thus very sexy, of course, especially if you have father issues. And who doesn't? It's furtive but powerful challenge to the paternal authority.
